Description

Technical Field

[0001] This invention relates to the field of modular underwater robot technology, and more particularly to a split-type modular AUV interface. Background Technology

[0002] With the increasing research and exploration of the ocean, the field of multifunctional underwater robot technology has also received increasing attention from researchers at home and abroad. However, the equipment that underwater robots can carry is limited, especially for micro-underwater robots. There is a lack of a standard interface to replace functional modules, which greatly restricts the development of multifunctional underwater robot technology. Based on this multifunctional modular development concept, developing a standard interface technology to enable modular underwater robots to diversify their functions and quickly replace and maintain them is one of the important issues in the field of underwater robot technology.

[0003] Currently, most domestic AUVs adopt an overall structural design, which has limitations in functional development, overall complex maintenance, and long maintenance cycles. Therefore, realizing a split modular AUV interface design is the primary issue to address in order to achieve diverse functions, reduce R&D cycles, and lower maintenance difficulty. Summary of the Invention

[0004] This invention provides an interface for a split-type modular AUV, which has the advantages of simple structure, reasonable design and standardized usage mode. It lays the foundation for modular design of AUV, greatly facilitates the use of modularization, and makes the serialization and standardized application of AUV a reality.

[0005] To address the aforementioned technical problems, this invention provides an interface for a modular AUV, comprising a housing, a standard male interface, and a standard female interface. The interface further includes a zero-position limiting block, a final-position limiting block, a sealing ring, a hexagonal set screw, M3*8 cylindrical head screws, M3*8 and M3*6 Phillips head countersunk screws, a movable mounting bracket, a mounting bracket rotating sleeve, an aviation plug, a mounting bracket rotating shaft, and a fixed mounting bracket. The housing has positioning holes for the standard interface. The inner sides of the standard male and standard female interfaces are respectively provided with a zero-position limiting block and a final-position limiting block. The standard interface has corresponding mounting holes on its inner side. Mounting brackets and aviation plugs are installed on both sides of the standard interface to ensure underwater electrical connection.

[0006] In a preferred embodiment of this solution, the inner diameter of the standard interface-male is equal to the outer diameter of the standard interface-female, and matching limiting blocks are provided at their relative positions, which are then connected and fixed by Phillips head countersunk screws.

[0007] As a preferred embodiment of this solution, the final position limiting block is an L-shaped arc structure and the zero position limiting block is a square arc structure. The longer section of the final position limiting block is a rectangular arc structure. When the zero position limiting block of the standard interface-male rotates to contact the final position limiting block of the standard interface-female, a sealed connection is achieved.

[0008] As a preferred embodiment of this solution, the standard interface-male and standard interface-female are provided with aviation plugs at their center positions for underwater electrical connection and underwater information transmission.

[0009] As a preferred embodiment of this solution, a sealing ring is provided at the connection between the housing and the standard interface to ensure the sealing performance of the interface.

[0010] As a preferred embodiment of this solution, the standard interface-male and standard interface-female are respectively provided with a fixed aviation connector and a movable aviation connector for fixing the aviation plug and ensuring the tightness of its electrical connection.

[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: This invention has the advantages of simple structure, reasonable design, and standardized use. It achieves both sealing and electrical connection in structural connection. The mechanical connection between modules is achieved by their own structure, without the need for external screw fastening, which can minimize corrosion. The installation and disassembly process only requires rotating the two modules by a certain angle. It realizes the standardization of interface technology for split modular AUV and provides a standard interface technology for modular AUV to achieve modularity. Attached Figure Description

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] like Figures 1-3 As shown, a modular AUV port connection device includes a housing 3, a standard interface-male 4, a standard interface-female 1, a zero-position limiting block 14, a final-position limiting block 13, a sealing ring 10, a hexagonal head screw 2 and a cylindrical head screw M3*8 12, a movable aircraft connector bracket 6, an aircraft connector rotating sleeve 7, an aircraft plug 8, an aircraft connector rotating shaft 9, a fixed aircraft connector bracket 11, Phillips head screws M3*8 15, and Phillips head screws M3*6 5. The housing has standard interface interfaces on both sides, and the housing is connected to the standard interface by hexagonal head screws. The standard interface-male 4 and standard interface-female 1 have positioning holes, and the limiting block is installed on the standard interface by Phillips head screws M3*8. The fixed aircraft connector bracket 11, the movable aircraft connector bracket 6, and the aircraft plug 8 are installed at the standard interface for electrical connection, and are connected by cylindrical head screws M3*8 12, the aircraft connector rotating shaft 9, and the aircraft connector rotating sleeve 7.

[0017] In practical applications, the inner diameter of the quasi-interface-male 4 is equal to the outer diameter of the standard interface-female 1. The two are provided with matching zero-position limiting blocks 14 and end-position limiting blocks 13. The mutual limiting of the zero-position limiting blocks and the end-position limiting blocks achieves the effect of rotation and sealing.
